Smart fan system based on stm32f407

1. Content and process

The main content of the project is to design and make a project based on stm32f407 Intelligent fan system , This intelligent fan system can measure whether someone appears , Whether the temperature is too high , Whether there is a fire hazard , This system perfectly solves the problems of waste of power resources and untimely handling in dangerous environments , It is a perfect representative of the development of smart home .

1.1 about stm32f407 Chip and development board learning

What we use is stm32f4 Series of chips , It's using stm32f407vgt6 Minimum system board , Yes 100 Pin ,82 individual GPIO Pin , be relative to stm32f1 In terms of series , It is a relatively high-end chip , Can complete a lot of woolen , Including the realization of Ethernet interface and other functions . First , First, we have an intuitive understanding of this chip , Then I read the data manual under the guidance of the teacher , Through the data book, we can clearly see the specific functions and usage of this chip , It is a chip with very high performance .

1.2 For temperature and humidity module DHT11 Learning from

DHT11 It is a temperature and humidity sensor with calibrated digital signal output , There is a resistive humidity sensor and a NTC Temperature measuring element .

 

1.3 For the study of photosensitive resistance

The photoresist module is most sensitive to ambient light , Generally used to detect the brightness of the light in the surrounding environment , Trigger data such as MCU or relay module

 

1.4 Learning about motor module

   Rated voltage ：3.4v

   Starting voltage ：0.15v

   Rated current ：800MA

   Rated speed ：34000

   Application field ► Radio-controlled helicopte ► Fixed wing fan ►DIY Four axis aircraft

 

1.5 Programming

Based on the program block diagram , It is divided into manual control and automatic control , The mode conversion between manual control and automatic control is automatically converted by pressing the key . In manual mode , You can switch the fan , Speed up , Deceleration and other functions . In automatic mode , The system can automatically identify whether someone appears , Then judge whether there is a fire hazard and select the switch of the fan .
